| 20100264129 | ELECTRODE SUPPORT STRUCTURE AND ELECTRIC HEATING DEVICE HAVING SAME - Provided is an electrode support structure in which local heating can be prevented from occurring in a workpiece during the electric heating. The electrode support structure is usable for applying a load to the electrodes used for the electric heating of a metal plate, and comprises at least two members, i.e., a first member to which the electrodes are fixed and a second member which receives the load from the first member or connects the first member to a load means. The support structure in which the two members are joined to each other through an elastic member can uniformly apply the load to the electrodes for electric heating so that the electrodes can uniformly contact with the workpiece, whereby the workpiece can be uniformly heated. | 10-21-2010 |
| 20100269559 | CONDUCTION HEATING APPARATUS AND HOT PRESS FORMING APPARATUS HAVING THE SAME, AND CONDUCTION HEATING METHOD - A conduction heating apparatus performs conduction heating while clamping a work to be hot press-formed by a clamping mechanism to apply tension to the work. The clamping mechanism has a stationary clamping member and a movable clamping member, a lifting up/down cylinder for the stationary clamping member and the movable clamping member, and tensioning cylinders that drive the movable clamping member along the planar direction of the work, and in conduction heating. The stationary clamping member clamps one side of the work and hold it, and the movable clamping member moves while holding the other side of the work according to thermal deformation of the work, which applies tension to the work corresponding to the thermal deformation of the work. | 10-28-2010 |
| 20100288008 | CONVEYOR APPARATUS AND HOT PRESS-FORMING APPARATUS COMPRISING THE SAME - A conveyor apparatus conveys work that was conduction heated at an energizing position to a processing position that is separated from the energizing position in the horizontal direction in order to perform hot press-forming, and comprises: a holding member that freely clamps both end sections in the lengthwise direction of the work that has been conduction heated; a drive mechanism that moves the holding member from at least the energizing position to the processing position; and a guide member that extends between the energizing position and the processing position and guides and supports the middle section in the lengthwise direction of the work that has been conduction heated and is being conveyed toward the processing position. A hot press-forming apparatus comprises the conveyor apparatus when conveying conduction heated work to a downstream process. | 11-18-2010 |
| 20100288009 | HOT PRESS FORMING APPARATUS AND HOT PRESS FORMING METHOD - A hot press forming apparatus that hot press forms a blank to process the blank into a formed product comprises: a conduction heating mechanism installed in the hot press forming apparatus, the conduction heating mechanism clamping the fed blank at a predetermined conducting position so as to be in a conveyance-stopped state, and performs conduction heating onto the blank; a die quenching type hot press mechanism installed in the hot press forming apparatus and disposed thermally isolated downstream of the conduction heating mechanism, the hot press mechanism hot pressing the blank subjected to conduction heating at a predetermined processing position; and a conveying mechanism installed in the hot press forming apparatus.
